Mega Man 9 offers a true 8-bit experience, bugs and all. The company's Hironobu Takeshita recently told Gamasutra that the download will have the look and feel of a NES-era release, and that things such as sprite flicker have even been included as a -- thankfully optional -- feature.
"Yeah, there were some things, like you couldn't have more than three enemies on the screen at once, so we had to make sure that that's how it stayed in our game. In the part with the dragon with the flame, [there should be] flickering, and whatnot," noted the game's producer. "In the options of this game, you can adjust that, unlike the old games. We purposely put some of those old-school bugs into this game, so it does recreate that feel." Now, if only Capcom could emulate blowing into the cartridge we'd be in retro heaven.
